Abstract: A graphite sheet can be combined with a base even without the need for use of an adhesive. A surface layer porous graphite sheet includes: a graphite layer and a porous layer arranged on one or both surfaces of the graphite layer. The porous layer has pores having a pore diameter X that is measured on a surface of the porous layer and pores having a pore diameter Y that is measured inside the porous layer and that is larger than the pore diameter X. A porosity in a cross section of the surface layer porous graphite sheet satisfies a predetermined condition.
